PURPOSE: To prevent deterioration in the tactile sense of a manual slide (or rotary) mechanism having a movement stopper. CONSTITUTION: A spring 20 fixed in an axis 16 is bent downward as to push a spherical body 24 to a hub 18. A plurality of dents, which are movement stoppers, to be fitted for the spherical body 24, are arranged concentrically on the shaft 16 and the spherical body 24 is successively and repeatedly detached from and fitted into the dents following the rotation of the axis 16. The tactile sense is not deteriorated even by wear by properly selecting the diameter of the spherical body and the diameter of dents. |
